Static electricity is typically generated by the contact and separation of materials. Whether it's a person's clothes against their skin or the contact and separation of a person's shoes when walking on an insulative floor. It's easy to generate a static charge! A static charge is in search of an electrical ground and ultimately - the earth.
Static builds on a person until they come into contact with something of a lower electrical resistance and ZAP! 99% of the time a person won't feel the discharge. It's constant, ongoing and relentless. If uncontrolled these discharges can wreak havoc on sophisticated electronic components. ESD Matting slows, controls and dissipates the static, ultimately allowing it to find ground without the disruption it so often causes on the way.
